TRlTU RATO R.

SPECIFICATION forming part of Letters Patent No. 343,075, dated June 1, 1886.

Serial No.'175,040. (No model.)

To all whom it may concern:

Be it known that I, LEWIS SHERMAN, of Milwaukee, in the county ofMilwaukee,and in the State of Wisconsin, have invented certain new and useful Improvements in Triturators; and I do hereby declare that the following isa full, clear, and exact description thereof.

My invention relates to machines for triturating, and will be fully described and claimed hereinafter. I

In the drawings, Figure l is a view of my device, partly in elevation and partly in section. Figs. 2 and 3 are details. Fig. 4 isa section on line ww of Fig. l. Fig. 5 is plan view.

A is the base upon which my machine rests.

Bis the table or counter.

Gis the platform that surrounds the Inortar D. rIhis mortar is mounted upon an arbor, D', which is driven by a belt, the mortal' being connected to the arbor by an annulus, d, from lugs d' of which binding` screws d2 project against the lower edge ofthe mortar. An annulus, E, is secured to the platform C, so as to extend around the edge of the mortar, and this annulus is perforated, as at E', each perforation to receive a bent end of a`wire, e; or the wire e may be connect-ed, as by a chain, to the platform. Each of these wires carries a pestle at its inner end, which hangs in the mortar. Any number of these pestles maybe used, according to the requirements ofthe work.

F is a group of two pestles, which are connected by a wire, f, and suspended from one end of another wire, g, which latter is pivoted at its end,opposite the pestles, to the platform C.

G is a lever that is pivoted to a standard, F', and this standard in turn is pivoted to a lug, h, on the base A. The lever G is of bellcrank shape, and its horizontal arm is supported by a block, g', while its vertical arm projects up through thev table and platform, where it is bifureated and straddles the wire g from below. The standard F' is connected by brace h' with another standard, F, which is pivoted also to a lug, h2, on the platform, so that-as the standard F' is vibrated, as will be hereinafter described, a corresponding movementwill be imparted to lever G, which in turn acting upon wire g will cause it to oscillate the group of pestles F in the mortar.

K is a shaft that has its bearings in brackets K', and this shaft, besides carrying tight pulleys band b', also carries a loose pulley, b2, which in turn carries on one of its faces a disk, b3, in which is a cam-groove, b4. The standard F2 is slotted near its lower end to receive a bolt, m, by which it is bound to a slotted link, m', from which a sleeved lug projects into the cam-groove b, so that the revolution 0f the pulley b2 and its disk b will cause the standard F2 and its companion F' to vibrate. The pulley b' is driven by the belt M, and another belt extends from the pulley about a like pulley, b5, on the arbor D', and the pulley b2 is driven by a belt, M', and as the latter pulley is loose on shaft K the standards F' and F2 will be vibrated independently of the arbor D'. The degree of vibration ofthe standards is regulated by adjusting the link m' on the standard F2. f N is a yoke, which carries suspended from its center a large pestle, O, the bottom of which rests in the bottom of the mortar, and

the ends of the yoke are pivoted each to a standard, one to standard F' and oneto standard F, the result being that as the standards and yoke are vibrated the pestle will be drawn slowly back and forth in the mortar. I propose at times to dispense with the large pestle and yoke, and simply to suspend a greater or less number of small pestles in the mortar, as I find that each pestle will do as much work individually when several are used as-when one only is used. By adjusting the bindingscrews d2 the position of the mortar may be so changed asy to make it more or less eccentric to the axis of the arbor. As the mortar revolves, the centrifugal force will tend to throw the matter being triturated out, but the small pestles upon thesides of the mortar will act as Scrapers to return it.

Having thus described my invent-ion,what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a triturating-ma chine, of arevolving mortar, an annulus surrounding said mortar, and carrying wires extending over its rim, and the'pestles attached to said wires, substantially as described.

2. The combination, with an adjustable revolving mortar and its arbor or shaft, of a power-shaft, belting connecting the powershaft with the mortar shaft, a cam grooved disk carried by said power-shaft, vibrating pestle-operating arms, and a slotted link engaging the groove of the cam-disk and connected to the pestle-operating arms, substanl tially as described.

3. The combination, with a revolving mortar, of a pestle suspended therein, ayoke, N, standards F F2, a revolving disk, b3, having oam-groove, and a link having a lug that works in the cam-groove, as set fort-h.
